Recently, the reporter interviewed the village of Guihe Sancun in Datian Township, Shouguang City, and saw that the vegetable farmer Dong Dage was putting wormwood sprouts in the shed. According to Dong Dage's introduction: The wormwood seedlings are taught by Men’s University. The yield between the seedlings is good. Not only does Artemisia selengensis produce high yields, but it is of good quality and does not bend. In addition to choosing seedlings that are consistent in their growth, the following two points need to be taken into consideration when the seedlings are grown:
The first is that the time between seedlings should be appropriate. If the time between the seedlings is too early, it is easy to spend the second time. Because the seed that is thrown into the ground does not grow at the same time after watering, it will inevitably cause some seedling seedlings to have been unearthed, and some seeds have just begun to germinate. On the contrary, if the time between seedlings is too late, many true leaves have already grown on the aerial parts of Artemisia selengensis. Excessive leaves will block the sight of the seedlings and cause difficulties in seedlings and seedlings, and the efficiency will be low. The underground parts will not be timely and the roots of seedlings will not be timely. Staggered growth results in "injury and no sputum" during the process of thinning and damages the roots of the remaining seedlings. It also causes unnecessary waste of water and fertilizer in the soil.
The correct time for the seedlings should be when the leaves of the Artemisia selengensis grow two true leaves and the true leaf size is about 0.5 cm. At this time, the seedlings not only ensure the effective excavation of effective seeds in the soil as much as possible, but also reduce the trouble of secondary seedlings. It also helps to maintain the same seedlings, which will facilitate later management and produce high-quality garland chrysanthemum. At the same time, during this period, the seedlings and seedlings are of a moderate size, which is not easy to block the sight line, and is easy to operate. By hand gently, the unqualified seedlings can be removed.
Followed by the seedlings, keep a reasonable seedling spacing. The production of garland chrysanthemum must first ensure sufficient spacing of seedlings in order to make the stalks of Artemisia selengensis grow as thick as possible, increase the weight of single culms, and reduce lodging. But at the same time, it should not be excessively widening the distance, because the spacing is too large, it is easy to cause the seedlings of Artemisia halodendron to fall down and reduce the overall benefits.
Dong Dago concluded through years of planting experience that the correct seedling spacing should be 2-3 cm. This distance can guarantee the highest overall benefit and ensure high yield and quality under the premise of ensuring the best weight and quality of a single tree.
